| Abstract: |
The Visible Broadband Imager (VBI) will be the primary first-light
instrument for the Advanced Technology Solar Telescope (ATST). It is
designed to observe the solar atmosphere at heights ranging from the
photosphere to chromosphere. High frame-rate detectors that sample the
FOV of up to 2.8 arcmin in diameter critically at the diffraction
limit of ATST's 4 meter aperture will provide near real-time speckle
reconstruction imaging. With its focus on high-spatial resolution, the
VBI will be addressing scientific questions related to the smallest
structures visible in the solar atmosphere with high photometric
precision. The capability to observe the solar atmosphere with a
cadence of about 3 seconds per reconstructed image will enable the VBI
to temporally resolve fast evolving structures. In this contribution
we present the major aspects of the current design of the VBI and
highlight some scientific questions related to fast evolving,
small-scale features within the solar atmosphere that the VBI will
address. |
